LANTERN ATTACHMENT.

Specification of Letters Patent.

Patented Dec. 11, 1917.

Application filed Aprilll, 1916. Serial No. 90,415.

To all whom it may concern.

Be it known that we, VALANDINGHAM DOUGHMAN and LLOYD D. GREENLAND, both citizens of the United States, and both residents of Mizpah, in the county of Koochiching and State of Minnesota, have invented certain new and useful Improvements in Lantern Attachments, of which the following is a specification, reference being had to the accompanying drawings.

This invention has relation to certain new and useful' improvements in attachments adapted to be secured to the globe of an ordinary kerosene burning lantern, the aim of our invention being to provide a lantern attachment of a simple and inexpensive nature, and of a compact and durable construction, which shall be capable of convenient and accurate adjustment in position upon the upper edge of an ordinary kerosene burning lantern to the end that the smoke, and gases, from the burner will be carried through said attachment and out of the globe thereby preventing any smoke at all times collecting within the globe.

Another object of our invention is to provide a lantern with an attachment which will prevent the same from becoming overheated as well as preventing the globe from becoming soiled or covered with soot and smoke.

With these and other objects in view, the present invention consists in the combination and arrangement of parts as will be hereinafter more fully described, and finally pointed out in the appended claim, it being further understood that changes in the specific structure shown and described may be made within the scope of the claim without departing from the spirit of the invention.

In the accompanying drawings forming a part of this specification, and in which like numerals of reference indicate similar parts in the several views Figure 1 shows a conventionally constructed kerosene oil burning lantern provided with our attachment.

Fig. 2 shows a portion of a lantern disclosing the globe and our attachment in section.

Fig. 3 shows a top view of our attachment disclosing the spring holder in position.

Fig. 4 is a lower end view of our attachment.

As conventionally constructed when the wick of an ordinary kerosene burning lantern is raised beyond a certain height, there is an incomplete .combustion which results in smoke and soot being generated which collects and is deposited within and upon the globe of the lantern thus covering the globe and obscuring the light.

In our invention we provide a simple and inexpensive attachment in the form of an open-ended flue comprising a. foraminous disk the arrangement being such that the disk is detachably secured to the upper end of the globe while the duct or flue extends downward and ends a suitable distance above the burner and flame of the lantern whereby all smoke and gas generated by the flame escapes through the flue and out of the globe preventing the globe from becoming soiled or obscured by the smoke and soot.

In carrying out the aim of our invention, we employ a foraminous disk 1, which is provided with a circumseribing rectangular flange 2, this flange being of such a size as to snugly fit upon the upper end of a conventionallv constructed lantern globe B. In the drawings, we have shown a lantern A pro vided with a globe B which is held in position by means of the usual spring wire securing frame I), secured to the usual top T, the lantern being shown as provided with the burner 0.

As disclosed in the drawings, the foraminous disk 1, is provided with a circular centrally disposed opening within which is flanged the upper tubular end 6 of a flue or duct 3, which gradually increases in diameter toward the lower end, as shown in Figs. 1 and 2, the lower end of the duct being flared outward.

As disclosed, the upper end of the duct or flue 3 is provided with a flange 4 to securely hold the same to the foraminous supporting member 1. The duct or flue 3 is of such a length that it terminates a suitable distance above the flame and burner of the lantern, as shown in Fig. 1, so that in turning up the wick beyond the height giving complete combustion the flame wil lenter the lower flaring end of the duct or flue resulting in the smoke, gas, and soot particles escaping through the duct or flue and out of the upper end of the same so that the globe will remain clean and will in no way become soot covered.

This duct or flue further performs an important function in that as the products of The forannna within the disk further insure a suflicient amount of air within the globe.

In view of the fact that the principal draft through the lantern is through the duct or flue 3 the flame is always held centrally below this duct thus insuring all products of combustion at all times escaping through the same even though the lantern be carried in a gale, or swung from side to side.

The foraminous disk further is provided with a predetermined number of openings so that there will be no likelihood of the draft on the outside of the flue being sufliciently great as to deflect the products of combustion and prevent the same from entering the flue.

The attachment further is simple and inexpensive in construction and both durable and eflicient in operation, and can be attached to the upper end of a lantern globe or removed therefrom with ease, accuracy, and despatch.

Having thus described our said invention what we claim as new and desire to secure by U. S. Letters Patent is The combination with a lantern and its chimney and means for holding the top of said chimney, of a foraminous disk having a circumscribing rectangular flange for engagement with the top of said chimney, said holding means fitting on said flange to hold the same in place, and an open-ended flaring tubular member secured centrally within said disk, the lower end arranged to be located above the burner of said lantern, all arranged as shown.

In testimony whereof we afiiX our signatures in the presence of two witnesses.
